Oracle : Ошибка ORA-01618

"redo thread %s is not enabled - cannot mount"
*Cause: The INIT.ORA parameter "thread" requests a thread that is not
enabled. A thread must be enabled before it can be mounted.
*Action: Shutdown the instance, change the INIT.ORA parameter and startup
mounting a different thread. If the database is open in another
instance then the thread may be enabled.
